Airflow control
Withdrawal 1. Disconnect the hose from the regulator (see. Photo in Chapter 4, Section 9). 2. Disconnect the connector. 3. Unscrew the bolts and remove the regulator from the intake manifold. Check 4. Self can determine the presence of voltage on the controller, the resistance of the controller, as well as closing the shutter on heating controller. If the valve is not closed in the presence of voltage and the normal resistance, then hand over control to the car wash to diagnose. 5. Note the position of the valve controller. At a temperature of 1419 ?� C, the gate must cover about half of the channel. As the temperature decreases the shutter opens more.

6. Apply the controller via auxiliary cables (one of them solder fuse), the voltage of the battery. 7. When heating current from the battery controller should override the valve channel (about 5 min). In this case, the controller is OK, follow the procedure from para. 10. 8. If the gate is closed for too long, check the resistance of the regulator. 9. If resistance differs from norm, replace the regulator. 10. Check the voltage on the controller by connecting a voltmeter between terminals a and b connector (see photo). The voltage should be about 12, and after 5 seconds down to 0. Otherwise, faulty wiring of the controller. 11. The controller may not work if there is no connection with the mass through the processing unit, in spite of the presence of voltage at terminal "a". Check the integrity of the wires from the controller to the processing unit. 12. Installation is performed in reverse order. Replace sealing ring.
